Last month when I visited Chicago for Lollapalooza, I squeezed in Tripadviser and Viator's number one tour in the US, Chicago Architecture River Cruise. It definitely lived up to it's hype. I didn't know that buildings could have so much history and meaning to them. Cheers to the beautiful skyline of the windy city! However, my recent trip to England opened my eyes to even more beautiful architectural marvels!
